Geosynthetics thickness tester

The Geosynthetics thickness tester is used to determine the thickness of textiles and textile products. It is suitable for measuring the thickness of various woven and knitted fabrics, and can also be used to measure the thickness of other uniform thin materials. It is the most important testing instrument for industries such as cotton weaving, knitting, bed sheets, handkerchiefs, and papermaking.

Applications

Used to determine the thickness of various geosynthetic materials under specified pressure and time. The sample is placed on the reference plate, and after a specified pressure is applied to the sample with a circular presser foot parallel to the reference plate for a certain period of time, the vertical distance between the two plates is measured, and the thickness of the sample is expressed as the average value of the test results.

Test Procedures

1. Instrument Leveling

Adjust the instrument's leveling device to ensure the sample is evenly stressed.

2. Sample Placement

Place the geosynthetic sample to be tested stably on the instrument's reference plate.

3. Indenter Alignment

Adjust the circular indenter to be parallel to the reference plate and align it with the test area of the sample.

4. Applying Pressure

Apply the specified pressure (selectable 2kPa, 20kPa, or 200kPa) to the sample using the precision mechanical pressure system.

5. Stabilization

Maintain the pressure for a period of time (following the duration required by the corresponding test standard) to allow the sample to stabilize.

6. Data Reading

Read the vertical distance between the reference plate and the indenter (i.e., the current sample thickness) using the digital display.

7. Result Calculation

Repeat the test at multiple points and take the average of all test results as the final thickness of the sample.
